'Application filed May 22, 1920. ESerial No. 383,354.

2' '0 all whom it may concern Be it known that I, THOMAS C. JOHNSON, acitizen of the United States, residing at New Haven, in the county ofNew Haven and State of Connecticut, have invented a new and usefulImprovement in Bolt- Action Guns; and I do hereby declare the following,when taken in connection with the accompanying drawings and thecharacters of reference marked thereon, to be a full, clear, and exactdescription of the same, and which said drawings constitute part of thisapplication, and represent, in Figure l. A broken view in side elevationof a bolt-action gun provided with a fillerblock in accordance with myinvention.

Fig. 2. A similar, but less comprehensive view, showing the rear end ofthe receiver as it appears when the filler-block is removed preparatoryto the installation of a leaf-sight mount or a telescope-sight mount,Fig. 3. A detached View in rear elevation of the receiver which isstripped except for my improved filler-block.

My invention relates to an improvement in thatclass of bolt-action gunsproviding for the installation on the receiver of the arm and close tothe eye of the user thereof, at the pleasure of the user, of aleaf-sight or a telescope-sight; the object of my present inventionbeing to provide for filling the cut in the rear end of the receiverwhen both of these sights are replaced by a sporting-sight on the barrelof the arm.

With these ends in view, my invention consists in a bolt-action gunhaving its receiver formed with an upwardly and laterally openingcartridge-receiving and ejection opening and with a transversemounting-slot located immediately in the rear of the said opening, and afiller-block provided at its forward end with a dovetail rib forinsertion into the slot and providedwith a rearward extension arrangedto overhang the rear end of the receiver, and formed at the right handof its overhanging end with a slot for the clearance of the bolt-handlewhen the same is lifted into its unlocked position.

In carrying out my invention, as herein shown, the receiver 2 of the gunis formed Specification of Letters fatent.

Patented 001;. 12, 1920.

I with the usual upwardly and laterally opening cartridge-receiving andejection opening 3. Immediately to the rear of this opening,

the upper face of the receiver is formed with a transverse dovetail-slot4 for the reception of a dovetail-rib 5 depending from and arrangedtransversely to the longitudinal axis of a filler-block 6, the rear endof which is formed with an extension or overhang 7 which overhangs therear end of the receiver by something over a third of the length of theentire block. The extension or overhang 7 of the filler-block is formedon its right hand side with a clearance-cut 9 for the clearance of thebolthandle 10 when the same is lifted into its unlocked or horizontalposition. The gun is also provided with a bolt 11 furnished at its rearend with a bolt-head 12, in front of which the handle 10 is mounted; butthe detailed construction of the gun may be varied as desired, since myinvention is directedsolely to its provision with a filler block to takethe place of the mounting 1 blocks of leaf and telescope-sights.

The filler-block as shown in the drawings has all of its corners andedges which are exposed when the block is in position on the gun,rounded, so as to prevent scratching other objects and to preventunnecessary wear and possible tearing of the guncase by sharpprojections.

By means of my filler-block, the user may restore the receiver tosubstantial integrity of form and appearance when he does not desire touse either of the two sights provided for use at the rear end of thereceiver, close to the eye. Without this block, he must leave the gun inan apparently mutilated and unsightly condition when he is not usingeither of the receiversights referred to. Moreover, when the gun is putin a gun-case or packed in a trunk, or in a suit-case or similarpackage, the sharp corners of the rear upper surface of the receiverwould be very damaging without the round-cornered filler-block to coverthem.

I claim: v

In a bolt-action firearm, the combination with a receiver having anupwardly and laterally opening cartridge-receiving and ejection openingand a transversely arranged, undercut mounting-slot located in the"upper face of the receiver at a point immediately in the rear of thesaid opening; of a detachable filler-block provided at its forward endwith a depending, transversely arranged rib forinsertion intothe saidslot, and at its rear end with an extension overhanging the rear end ofthe receiver, and formed on its right-hand side with a clearance-cut forthe reception of the bolt-handle when the same is in its elevatedposition,

10 the said filler-block being of the same width as the said receiverand having all of its outstanding corners and edges rounded off. Intestimony whereof, I have signed this specification in the presence oftwo subscribing witnesses. V
